摘要： PROBLEM TO BE SOLVED: To prolong the life of a radiant tube and hence ensure low NOx by providing combustion interruption time not performing exhaustion from the radiant tube, within combustion set time of alternate combustion as reguired, and adjusting a ratio of combustion time and the combustion interruption time according to a load to adjust furnace temperature. SOLUTION: Upon alternately combusting regenerating burners 2a, 2b disposed at opposite ends of a radiant tube 1 for the respective burners 2a, 2b there is provided at need combustion interruption time not performing exhaustion from the radiant tube 1 within set time of the alterenate combustion whereby a ratio of the combustion time and the combustion interruption time is adjusted in response to a load. When the combustion time does not exceed set time, the same burners 2a, 2b are also operated for the next combustion set time without performing switching of the burners 2a, 2b to add combustion time, and when the added combustion time exceeds the set time, the burners 2a, 2b are switched. Thus, good temperature distribution is maintained.

摘要： PROBLEM TO BE SOLVED: To enable the recirculation combustion of an exhaust gas by opening the end part of a recirculation path that communicates with an exhaust gas path in a fuel-injecting chamber, and sucking and mixing the exhaust gas at the exhaust gas path via the recirculation path by the injection pressure of a fuel. SOLUTION: In a burner, the edge part of a recirculation path 4 that communicates with an exhaust gas path 3 is opened into a chamber 1 that injects fuel, and the exhaust gas of the exhaust gas path 3 is sucked and mixed by the injection pressure of the fuel via the recirculation path 4. The recirculation path is constituted at the chamber for injecting the fuel at each of a pair of regenerative burners after being installed at both ends of a radiant tube, and an exhaust gas is sucked via the receirculation path due to the injection pressure of the fuel from the fuel injection chamber of the regenerative burner in exhaust state into the fuel injection chamber of the regenerative burner in combustion state.

摘要： PURPOSE: To improve efficiency by extracting a feedable area using the existing pipe resistance value, and estimating the generation of turbid water from the change of flow quantity pipe by pipe in the feedable area under construction and in the whole supply system before construction. CONSTITUTION: A system user indicates a specific pipe such as a work pipe from an input part 2 and specifies it to a processor 1. The processor 1 extracts pipes, connected to this work pipe through nodes other than valves, as a water failure pipe area. The processor 1 then computes the whole resistance from a water supply source node to each node on the upper reaches side node and lower reaches side node of each pipe and the upper reaches side pipe of each node in parts other than the water failure pipe area and determines so that the whole resistance becomes the minimum, thus locating an isolated pipe area. The processor 1 further computes the flow quantity in a water feedable area and the whole pipe network, and in the case of a flow ratio being changed to the extent of exceeding '2', it is so estimated that pipe inner surface attachment is separated to have generated turbid water. The processed result of the processor 1 is displayed on a display part 4. The efficiency and convenience of a system can thereby be improved.

摘要： PURPOSE:To make it possible to carry out respective flow rate control for a fluid for dilution and a fluid for increasing heat with both fluids mutually related by setting a value that is the addition of the operational output of a heat quantity controller and the value of flow rate that is derived from a balance formula for heat quantities in mixing to a flow rate controller which constitutes a flow rate control loop for the fluid for increasing heat. CONSTITUTION:A calculator 11b derives the value of flow rate of a fluid for dilution from a balance formula of Wobbe index in the mixing of a fluid for receiving heat, fluid for dilution, and fluid for increasing heat. The constitution is that this value is set in a flow rate controller 8b and at the same time a calculator 11c derives the value of flow rate for the fluid for increasing heat from a balancing formula of the quantities of heat in mixing. Further, the calculation to add the operational output of a heat quantity controller 6 to this flow rate value is carried out and the value of the calculation is set to a flow rate controller 8c. With this arrangement, when the flow rate of the fluid the heat quantity of which is controller the heat quantity vary, it is pos sible to control respective flow rates with the fluid for dilution and the fluid for increasing heat mutually related.

摘要： PROBLEM TO BE SOLVED: To cool members such as a valve disc or casing and to improve heat resistance by forming a vent part at an upstream side of the disc to close an air supply side at the time of exhausting, and supplying a small amount of the air from a vent part via a periphery of the disc even at the time of closing it. SOLUTION: When a valve disc 7 is forwarded to be brought into contact with a valve seat 6 at the time of burning the regenerative burner 4, a valve part of an exhaust passage 2 is closed, and the valve part of an air supply passage 1 is opened. Accordingly, the air from an upstream side of the passage 1 is supplied from a passage 3 to the burner 4 via a valve seat 5 for burning. The exhaust gas fed via the burner 4 is exhausted from the passage 3 at the passage 3 via the seat 6 by suction of an exhaust blower. In this case, ambient temperature air of the passage 1 is fed from a vent hole 11 of a plate 10 to a gap 12 between the hole 11 and a valve disc 7 by suction of suction of an exhaust blower, fed via a periphery of the disc 7, and exhausted via the passage 2 together with exhaust gas. At this time, the ambient temperature air fed from the passage 1 cools the disc 7 and the casing.
